This is another movie released in 1937 but with 1938 in the title, so I'm including it. MGM released "The Broadway Melody" in 1929 and it won the Oscar for Best Picture that year. Subsequently MGM released three more musical showcase pictures: "The Broadway Melody of 1936", "The Broadway Melody of 1938", and "The Broadway Melody of 1940". These last three all starred Eleanor Powell. This one also includes Judy Garland, Buddy Ebsen, and (1938 favorite of mine) Billy Gilbert.
